I'm working on trying to get my stand-alone Toshiba DR-1 DVD burner back to life. Inside this unit is a standard PC-IDE DVD-RAM drive. Now this is a rather old device - one of the first stand-alone DVD burners - and there's many owners out there whose drive has started misbehaving.
A bit of research on the AVForums site indicated that the LG H10N drive works as a drop-in replacement in the Tosh DR-1. I was only able to source an H12N drive. I've had some limited success getting the drive working, but I've backed myself into a corner somewhat.
The standard UL-02 firmware worked correctly in the Toshiba. However, it was region-locked. Since the unit, with the old drive, was region-free, I naturally wanted to sort that out. I experimented with many of the RPC1 firmwares on the forum, however the DR-1 always complained that the disk was unreadable and should be checked for damage.
At one point, I thought I'd got it working region-free, but it eventually started stating that disk playback was unauthorised (grr!). I think through my own confusion, I'd managed to think I'd flashed RPC-1 when I hadn't! (d'oh!)
I've taken a look at the original drive's information by hooking it to my PC. It seems the unit was made region free by setting the region to 'None', although it's still reporting as RPC-2. So, I'm deducing that the DR-1 doesn't accept an RPC-1 drive (giving the 'disk dirty' message). I got the drive to play DVDs by using one of TDB's 'Auto' firmwares - however, since the drive no longer has any region changes left, this is useless since the Auto firmwares seem to need there to be at least one change left. I'm stuck with the drive in R1, when (if anything...) I'd really prefer R2.
Is there anything I can do to get out of this? Is it at all possible to reset the number of user region changes remaining, short of using an RPC-1 firmware?
I think I might be SOL here...
